Libevent最新稳定版2.0.16在vs2010下编译并编写webserver测试用例

下载

libevent2.0.16稳定版

https://github.com/downloads/libevent/libevent/libevent-2.0.16-stable.tar.gz

进入VS2010命令提示

d:

cd libevent-2.0.16-stable

nmake /f Makefile.nmake

编译成功生成

libevent.lib          libevent_core.lib     libevent_extras.lib

用vs2010 创建一个win32控制台应用程序，项目名称Httpd，取消为解决方案创建目录选项,位置d:\test

然后两个下一步，应用程序类型选择控制台应用程序，附加选项勾选空项目，其他选项空，完成。

新建Httpd.c,输入下面代码
#include <stdio.h>

#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <winsock2.h>

#include <event.h>
#include <evhttp.h>

void root_handler(struct evhttp_request *req, void *arg)
{
    struct evbuffer *buf = evbuffer_new();
    if(!buf){
        puts("failed to create response buffer");
        return;
    }

    evbuffer_add_printf(buf, "Hello: %s\n", evhttp_request_uri(req));
    evhttp_send_reply(req, HTTP_OK, "OK", buf);
}

void generic_handler(struct evhttp_request *req, void *arg)
{
    struct evbuffer *buf = evbuffer_new();
    if(!buf){
        puts("failed to create response buffer");
        return;
    }

    evbuffer_add_printf(buf, "Requested: %s\n", evhttp_request_uri(req));
    evhttp_send_reply(req, HTTP_OK, "OK", buf);
}

int main(int argc, wchar_t* argv[])
{
 struct evhttp *httpd;

 WSADATA wsaData;
 DWORD Ret;
 if ((Ret = WSAStartup(MAKEWORD(2, 2), &wsaData)) != 0) {
  printf("WSAStartup failed with error %d\n", Ret);
  return -1;
 }

    event_init();

    httpd = evhttp_start("0.0.0.0", 18505);
    if(!httpd){
  return 1;
 }

    evhttp_set_cb(httpd, "/", root_handler, NULL);
    evhttp_set_gencb(httpd, generic_handler, NULL);

 printf("httpd server start OK!\n");

    event_dispatch();

    evhttp_free(httpd);

 WSACleanup();
    return 0;
}

复制include 和libs

mkdir D:\test\httpd\include\
xcopy /E /H /R D:\libevent-2.0.16-stable\include\* D:\test\httpd\include\
xcopy /E /H /R D:\libevent-2.0.16-stable\WIN32-Code\* D:\test\httpd\include\
xcopy /E /H /R D:\libevent-2.0.16-stable\*.h D:\test\httpd\include\
mkdir d:\test\httpd\libs
copy D:\libevent-2.0.16-stable\*.lib D:\test\httpd\libs\

进入配置管理器，设置活动项目为release。

设置release 的项目选项

C++
常规\附加包含目录 .\include;.\include\event2
代码生成\运行库 多线程 (/MT)
高级\编译为 编译为 C 代码 (/TC)
链接器
常规\附加库目录 .\libs
输入\附加依赖项 ws2_32.lib;wsock32.lib;libevent.lib;libevent_core.lib;libevent_extras.lib;%(AdditionalDependencies)
输入\忽略特定默认库 libc.lib;msvcrt.lib;libcd.lib;libcmtd.lib;msvcrtd.lib;%(IgnoreSpecificDefaultLibraries)

注意%(AdditionalDependencies)不能漏掉，否则会报编译错误
错误 1 error LNK2001: 无法解析的外部符号 __imp__CryptGenRandom@12 D:\test\httpd\libevent.lib(evutil_rand.obj) httpd

F6编译成功

CTRL+F5执行程序

显示服务

httpd server start OK!

在浏览器输入

显示

Hello: /

整个Libevent2.0.16就这样成功使用了。
